Geothermal power plants can potentially cause natural disasters such as earthquakes. This is mainly due to the process of injecting fluids into the earth to extract heat, which can induce seismic activity by altering the stress along fault lines. Enhanced geothermal systems, which involve fracturing rock to create pathways for heat extraction, have been linked to increased frequency and sometimes larger magnitude earthquakes, as exemplified by the 2017 Pohang earthquake in South Korea triggered by such a project

. Other related geological hazards include land subsidence caused by fluid withdrawal without balanced reinjection, which can lead to ground sinking and surface instability

. Additionally, geothermal areas are often located in tectonically active regions, increasing the risk of seismic and volcanic events, landslides, and hydrothermal eruptions

. In summary, the primary natural disaster potentially caused by geothermal power plants is induced earthquakes, along with associated hazards like land subsidence and hydrothermal eruptions in some cases
